Add new module to install and configure AWS CLI

[ausbru87]

Create a new module that automates the installation and basic configuration of the AWS CLI. This module should:

• Download and install the latest stable AWS CLI package
• Support popular operating systems (Linux, macOS, Windows)
• Document prerequisites and installation steps
• Optionally allow configuration of default credentials/profile via environment variables
• Provide example usage and verify installation in a post-step

Resources:

• AWS CLI Official Docs
• AWS CLI Configuration Docs

This will expand the registry to better support cloud automations and simplify workflows for users needing AWS capabilities.
